the economy beginning to come back. and what you saw today is, the president gave a meditation on freedom and equality. it was a president who else felt free. >> and so give me one indelible image from these hours we spent together today as you watched. >> oh, the one has got to be when the president turned back. when he turned back and looked over that mall and said he wanted to savor this moment. an african-american president, the first in our history, re-elected and giving a second inaugural address. >> on martin luther king day. thank you george. >> thank you. >>> and today is also a time to take stock of the last four years. we want to show you some images that say it all. this is president obama, four years ago. and today. the marathon of the past four years etched on his face. and he would say, in his graying hair. and michelle obama holding the bible as her husband took the oath then and today. michelle obama. and the girls, sasha and malia. what a difference four years makes in the lives of these young women. >
